Why You Should Start Growing Rhubarb
Nutritional
There are several reasons why one might consider adding rhubarb to their garden. One of those being its nutritional benefits. Rhubarb is a low-calorie vegetable that offers a range of essential vitamins and minerals. It is a good source of fiber, vitamin C, vitamin K, calcium, and potassium. Additionally, it contains antioxidants and other beneficial compounds, such as anthocyanins and quercetin, that have been linked to various health benefits. However, it’s important to note that the leaves of the rhubarb plant are toxic and should not be consumed. Only the stalks should be eaten.
Growing Rhubarb Is Easy
Rhubard is incredibly easy to grow. It is a hardy, low-maintenance plant that can tolerate a wide range of soil and weather conditions. Once established, it can produce stalks for up to 20 years with minimal care. Additionally, the pest pressure on rhubarb is virtually non-existent. The leaves of the rhubarb plant contain oxalic acid, which is toxic to many insects and animals. This may be why pests are deterred from feeding on the plant.
Rhubarb Is Versatile
Rhubarb can be used in a variety of sweet and savory dishes, from pies and crumbles to chutneys and sauces. Its tart flavor pairs well with fruits like strawberries and raspberries, as well as with meats like pork and chicken.
Overall, adding rhubarb to your garden can provide both nutritional and culinary benefits, while also promoting sustainable gardening practices.

Soil Conditions For Growing Rhubarb
Rhubarb thrives in well-draining soil that is rich in organic matter. Ideally, the soil pH should be between 5.5 and 6.8, which is slightly acidic. It’s important to avoid soil that is heavy in clay or compacted, as this can lead to poor drainage and root rot. To improve soil drainage, you can mix in peat, coco coir, perlite, or vermiculite.
To prepare the soil:
- Loosen the soil: Dig down at least 12 inches to ensure the roots have room to grow.
- Amend the soil: Add plenty of organic matter such as compost or aged manure to improve fertility and drainage.
Nutrients
Rhubarb is a heavy feeder, meaning it requires a lot of nutrients to grow.
- Before planting: Incorporate a balanced, slow-release fertilizer into the soil.
- Annually: Top-dress the plants with compost or aged manure each spring before growth begins.
- Supplement: During the growing season, apply a nitrogen-rich fertilizer if the plants appear weak or pale.
When to Plant Rhubarb
Timing is critical for rhubarb to establish itself and thrive. Plant rhubarb crowns or seeds in early spring, as soon as the soil is workable and before the last frost date. This gives the plant a chance to develop strong roots before summer heat arrives. If planting in colder climates, consider the following tips:
- Last frost date: Check your local estimated last frost date and plan to plant rhubarb about 2-3 weeks before it.
- Soil temperature: Ensure the soil temperature is at least 50°F for optimal root establishment.
- Fall planting: In mild climates, rhubarb can also be planted in the fall, allowing the plant to establish before winter dormancy.
Growing Rhubarb From Seed
You can grow rhubarb either from seed or from crowns (established root clumps), though each method has pros and cons.
Growing from Seed
- Pros: Cost-effective and offers the opportunity to grow unique varieties.
- Cons: Takes longer to mature (2-3 years before harvesting) and can be more challenging to establish.
To grow from seed:
- Start seeds indoors 8-10 weeks before the last frost date.
- Soak seeds in water for a few hours before planting to improve germination.
- Plant seeds ½ inch deep in seed trays filled with a quality seed-starting mix.
- Transplant seedlings outdoors after the danger of frost has passed.
Growing from Crowns (Starts)
- Pros: Faster results, with the potential to harvest in the second year.
- Cons: Slightly more expensive upfront.
To grow from crowns:
- Plant crowns as soon as the soil is workable in spring.
- Purchase disease-free crowns from a reputable supplier.
How to Plant Rhubarb
Whether planting seeds or crowns, follow these steps:
- Choose a location: Select a spot with ample sunlight and space for the plants to spread (at least 3 feet apart).
- Dig holes: Make holes 1-2 inches deep for seeds or 2-4 inches deep for crowns.
- Place the seeds or crowns: Plant seeds ½ inch deep or crowns with the buds just below the soil surface.
- Backfill: Gently fill the hole with soil, firming it lightly.
- Water: Thoroughly water after planting and keep the soil consistently moist.
Harvesting Rhubarb
Rhubarb should be harvested in the spring, typically starting in late April or early May, when the stalks are thick and firm. Here are some steps to follow when harvesting rhubarb:
- Wait until the plant is at least two to three years old before harvesting any stalks. This allows the plant to establish a strong root system.
- Choose stalks that are at least 10 inches long and 1 inch in diameter. Do not harvest any stalks that are thin or spindly.
- Grasp the stalk near the base, and gently twist and pull it away from the plant. Do not cut the stalks, as this can damage the plant.
- Remove the leaves from the stalks, as they contain high levels of oxalic acid and can be toxic if consumed.
It’s important to note that you should not harvest more than one-third of the plant’s stalks at a time. This allows the plant to continue to grow and produce more stalks throughout the season. Additionally, you should stop harvesting rhubarb by mid-summer, as the plant needs time to store energy for the next growing season.
In conclusion, growing rhubarb is a great way to add a flavorful and nutritious vegetable to your garden. To ensure optimal growth, make sure to plant in well-draining soil that is rich in organic matter, fertilize regularly, and start from seed or purchase established plants. With a little bit of care and attention, you can enjoy delicious rhubarb for years to come.
